  • Consistency: Transmission should look/feel oily like engine oil or brake fluid.
  • Location of leak: Transmission leaks tend to be found towards the front of the vehicle and in the middle.

Take Steps to Prevent Transmission Problems

With more advanced automatic transmission systems available, it’s important to make sure that the right transmission fluid is being used in your vehicle and that it’s being filled to the appropriate level.
